All of which has me wondering again why so many idiots are attracted to this site.
Oh well, that appears to be the main function of the web for so many, a hall of mirrors to reflect your favourite delusions.
Most of you are so thick you won’t even figure out what the above refers to.

The problems are indeed "immense". But they are not "teething" problems.

Renewables, apart from hydro which has siting problems, don't have the necessary energy density. The backup, batteries, are a mature technology. There is room for incremental improvement, but no great leap forward. That means fossil fuelled source power must continue to run as backup; so you are paying twice for the same electricity demand.

Yes I have seen that. Of course getting it to run more than 20 seconds is the next challenge. Fusion is always about 40 years away. Unfortunately. I am a believer in nuclear.

But the naysayers say "what about Chernobyl". An old design, and dodgy maintenance.

"What about Fukushima"? - built on unstable ground, and a 15 metre tsunami knocked out the power supply (battery backup would have kept system power online),  the cooling system didn't cover the reactors.

"What about Three Mile Island"? Another old design, mechanical and human error.

So what has changed? New designs, new Programmable Logic Controllers to take the human error out of it.

Chernobyl was caused by human error with safety drill.

Fukishima was earthquake which it survived yet had design flaw with backup generators for coolant placed in basement which was flooded by tsunami which drowned them.

Earthquakes aren't really a problem here fault line is east of here from NZ up to Indonesia.

Uranium is radioactive while it's in the ground before it's mined for some reason people ignore this fact.

Nuclear runs flat out for fuel cycle which means cheaper off peak electricity at night when cars will be recharged it also means people could stop burning gas and wood for fires to heat in winter and allow airconditioning to be used at night in summer.

"The research team says that the solar flow battery produced through the collaboration has set a new record efficiency of 20 per cent, besting most commercially available silicon solar cells, and was 40 per cent more efficient than the previous record holder for solar flow batteries, also developed by the Jin lab."

"Overall, the research team found that the new system’s long life and 20 per cent efficiency made it the best solar flow battery device yet.

“That’s 20 per cent efficiency any time you like,” Professor Jin said. “You can use the solar electricity right away during the day and get 20 percent, or you can use it in the evening from storage and get 20 per cent.” "

20% really?

Do you understand the meaning of the term ‘always’ in this context?
